Oil burner testing system - has timing element to adjust ignition delay, with display showing output of timer or photoelectric sensor

摘要

The inspection instrument is used in oil burners with a monitoring circuit. A specified limiting value for the ignition delay is adjusted by means of a timing element. When the limiting value is exceeded a signal is generated by means of the timing element. when the limiting value is not reached, a second signal is generated by means of the photoelectric current of the light sensor. The first signal generated is used for operating the display.
